Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158124, here are decompositions:
- 11 + 158113 = 158124
- 47 + 158077 = 158124
- 53 + 158071 = 158124
- 107 + 158017 = 158124
- 173 + 157951 = 158124
- 191 + 157933 = 158124
- 193 + 157931 = 158124
- 223 + 157901 = 158124
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 158,124 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 158124 first appears in π at position 88,629 of the decimal expansion (the 88,629ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
